Yes. Anything to get the kids away from the computer or gaming console just for part of the day is great. My kids are not on basefook or ginstaram at all and they still play a lot, my eldest son more so since upgrading. I pull out old photos, plug in the electric guitar, whatever it takes to pry them away.
Your gramophone looks like it's in good shape, your LP like new. I am happy your kids got to experience it.
